Our thinking about defence and security is shaped by ideas. What we see depends on our vantage point and the lenses we apply to the world. Governments, military and business leaders are seeking to maximise the value they gain from scarce resources by becoming more 'strategic'. Standing on the shoulders of the giants of strategy from the past helps us see further and more clearly into the future. This series is aimed at those looking to learn more about strategy and how to become more strategic – leaders, practitioners and scholars. This podcast series, co-chaired by Professor Beatrice Heuser and Paul O'Neill, examines the ideas of important thinkers from around the world and across the ages. The ideas, where they came from and what shaped those whose ideas shape us now. By exploring the concepts in which we and our adversaries think today, the episodes will shine a light on how we best prepare for tomorrow.
